ABSTRACT

The invention relates to a dyeing composition for keratinous fibres and in particular for human keratinous fibres such as hair, comprising, in a suitable medium for dyeing, at least one oxidation dye precursor chosen from 3-methyl -para-aminophenol, 2-methyl-para-aminophenol and 2-hydroxymethyl-para-aminophenol, and their addition salts with an acid, as coupling agent, at least 2-methyl-5-aminophenol, or one of its addition salts with an acid; and at least one para-phenylenediamine and/or one bis-(phenylalkylenediamine) or one of their addition salts with an acid as oxidation dye precursor.

Oxidation dye composition for keratinous fibres comprising a para-aminophenol, 2-methyl-5-aminophenol and a para-phenylenediamine and/or a bis(phenylalkylenediamine).

The present invention relates to a dyeing composition for keratinous fibres, and in particular for human keratinous fibres, comprising, in combination, at least one para-aminophenol, 2-methyl-5-aminophenol and at least one para-phenylenediamine and/or one bis(phenylalkylenediamine), and to the dyeing process using such a composition and implementing development by an oxidizing agent.

It is known to dye keratinous fibres and in particular human hair, with dyeing compositions containing oxidation dye precursors, in particular ortho- or para-phenylenediamines, ortho- or para-aminophenols, generally known as "oxidation bases" and coupling agents, also known as dyeing modifiers, more particularly aromatic meta-phenylene diamines, meta-aminophenols and meta-diphenols, which allow the "foundation" colourations obtained by the condensation products of the oxidation bases to be modified and to be enriched with glints.

In the field of oxidation dyeing of hair, oxidation dye precursors and coupling agents are sought which allow a colouration having a satisfactory resistance to light, to washing, to bad weather, to perspiration and to the various treatments to which hair may be subjected to be imparted to the hair, and to obtain a wide range of colour shades.

3-Methyl-para-aminophenol, as well as its use in dyeing compositions for keratinous fibres, in combination with 2-methyl-5-aminophenol as coupling agent and paraphenylenediamine or 2,5-diaminotoluene, are known and described in U.S. Pat. No. 4,883,656.

However, such a combination does not provide, after application to keratinous fibres, a sufficiently resistant colouration.

The Applicant has just discovered, and this forms the subject of the invention, that the use of 3-methyl-para-aminophenol, 2-methyl-para-aminophenol and/or 2-hydroxymethyl-para-aminophenol as oxidation dye precursors, in combination with 2-methyl-5-aminophenol as coupling agent and at least one para-phenylenediamine and/or one bis(phenylalkylenediamine) of formula (I) or (II) defined below as oxidation dye precursor, makes it possible to obtain, in the presence of an oxidizing agent, in an acidic or alkaline medium, after application to keratinous fibres and in particular human hair, colourations with red or coppery shades and which have a good resistance to light, to washing, to bad weather, to perspiration and to the various treatments to which hair may be subjected.

The subject of the present invention is thus a composition for dyeing keratinous fibres, in particular human keratinous fibres such as hair, comprising, in a suitable medium for dyeing:

at least one oxidation dye precursor chosen from 3-methyl-para-aminophenol, 2-methyl-para-aminophenol and 2-hydroxymethyl-para-aminophenol, and their addition salts with an acid;

as coupling agent, at least 2-methyl-5-aminophenol or one of its addition salts with an acid; and

at least one oxidation dye precursor chosen from the para-phenylenediamines and the bis(phenylalkylenediamines) of formulae (I) and (II) below, as well as their addition salts with an acid.

The subject-of the invention is also a dyeing agent containing several components, the first component of which contains oxidation dye precursors and the coupling agent defined above and the second component an oxidizing agent.

Another subject of the invention relates to the ready-to-use composition, containing the various agents used for dyeing keratinous fibres defined above and an oxidizing agent, in an alkaline or acidic medium.
